Minimum arrow weight?

[Mole trapper]

Hi all,
Just a quick question?
If I have an all up weight of 586grains consisting of an Easton gold tip arrow and a zwickey delta broadhead theoretically what would you consider the minimum draw weight to launch that effectively ar small species deer ( roe here in Europe).
I have a a slickstick doing 40 @ 28" draw, I pull to 30" so I'm thinking I am drawing roughly 46 lbs.
This set up shoots very sweet, and accurate too when I am on form .
Thanks for taking the time to read this.

If you can put that arrow where you want it to go at 15m to 20m you should be good to go.

Thanks for the reply,  really appreciate it , 15 yards is my maximum,  so that would work fine.

Get the broadhead shaving sharp and you will be just fine.

I shoot 43# right now, 27" draw. 565gr arrow. Used the same arrow when I was at 47#

Your setup could be lethal on deer three times the size of roe deer.

Reh are not that big an animal, you'll be fine with whatever shoots straight and flies well.
